The Cybersecurity Maturity Model Certification (CMMC) is a framework established by the Department of Defense (DoD) in 2019 to ensure that defense contractors adhere to cybersecurity standards specified in NIST SP 800-171. The main objective of CMMC is to safeguard sensitive data, including Federal Contract Information (FCI) and Controlled Unclassified Information (CUI), while enhancing the security of the defense supply chain.
In the past, defense contractors could self-evaluate their compliance with DoD security standards. However, the CMMC mandates that most contractors now undergo independent assessments conducted by certified third-party organizations. These evaluations will be carried out by CMMC Third Party Assessment Organizations (C3PAOs), which are accredited and trained by Cyber AB, the official body overseeing CMMC certification.
It is important to understand that even though CMMC will be phased in over time, it does not necessarily follow that you have more time to achieve CMMC certification. Your organization, for example, could be far down the supply chain from a contractor subject to CMMC in Phase 1, in which case that contractor must flow down CMMC requirements to your organization at that time.
